To all whom it may concern:

Be .1t known that we, MARTIN NYsTnoM- vand Lotus TAXoN, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Veneer-Taping which thefollowing is a specification.

Our invention relates to 4taping machines for securing the edges ofveneers together and at the same time crowding the tw pieces tightlytogether, and the objects of our invention are, first, to secure a stripof paper or cloth over the meeting edges of the pieces of veneer;second, to provide means for quickl drying the moistened tape thusapplied; t iird, to positively crowd the edges of the veneer together;fourth to make a simple, cheap and durable machine and other feature tobecome apparent'from the description to follow.

In machines of this class an important feature is to crowd the edges ofthe two pieces of veneer tightly together at the time that the securingtape is being fastened vto the same and this is accomplished in ourmachine by positively moving that portion ofthe clamping wheels, whichis in contact with the pieces of veneer, toward each other, whichobviously moves the pieces of veneer tightly together, and the edges ofthe veneer are prevented from lapping over4 one another by the pressureof the upper and lower clamping wheels. The movement of a portion of theclamping 'wheels toward each other is permitted by having the rims ofthe wheels made in sections, sufficient spring for such movement being`afforded in the spokes.

To describe our invention so that others versed in the art to which itpertains may make and use the same we have illustrated ity on theaccompanying three sheets ofdrawings forming a which y l `igure 1, is a.plan view of a machine embody-ing our invention partly broken away forthe purpose of illustration; Fig. 2,`is a cross section on line 2-2 ofFig. 1.; Fig. 8,

1s a cross section on line 3-3 of Fig. 1; A

Fig. l is a detail sectional View showing a `f raising and loweringdevice for the upper pressure wheels; Fig. 5, is a plan view of thelower pressure wheels enlarged; Fig. 6,- 1s a side elevation of theupper and lower pressure wheels enlarged; and

Fig. 7, is a section'on line 7 -'`7 `of Fig. 6.

Machine, of-

part of this specification in -sion of the springs Similar referencecharacters refer to similar parts throughout the several views.

The machine consists of a suitable frame 10 which maybe made of wood andis provided with a table 11, and the pressure wheels etc., which aremounted on said frame. The mechanism above the table 11 comprises theupper pressure wheels 12,l 13 and 14, the water receptacle 15 and thetape reel 16, while the mechanism below the'table .11 comprises thepressure wheels, 17, 18 and 19. p The'wheels 17 and 18 are rigidlymounted on shaft 20, mounted in frame 10 Vand driven bymeans oftheconnecting gears 21 `from shaft 22 on which is provided a pulley 23connected by belt 24 to pulley 25 on shaft 26 ,on which is mounted atight pulley 27 and aloose pulley 28. These pulleys 27 and 28 areconnectedby the-usual shifting belt to a source of power not shown.

Theshaft 20 is slowly rotated clockwise as viewed in Figs. 2, 3 and 6,which of course rotates the wheels 17 and 18 in the same direction. Thewheels 12 and 14 above the table 11 are mounted on shaft 29 looselyjournaled in the bearings 30 on the free end of the hingedv frame 31pivoted at 32 to frame 10, and are arranged to rest on the wheels 17 and1S, so that when the wheels 17 and y18 are rotated the wheels 12 and 14will' be rotated through the frictional contact therewith. It is clearthat if a piece of veneer or other material is placed between the lowerwheels 17 and 18 and the upper wheels 12 and 14 and the wheels arerotated as described the veneer will be moved along between the upperand lower wheels. To properly feed t-heveneer through between theIwheels it is necessary to have considerable pressure exerted against theveneer and this is done by having the upper wheels spring pressedagainst the lower wheels by the coiled ex'iand'ing springs 33 interposedbetween the ree ends of frame 31 and the brackets ,34 secured to framel0. The tenl 33 can be adjusted by the hand screw 3 It is necessary tolift the wheels 12 and 14 up away from wheels17 and 18 to stop theveneer from feeding through the niachine and this is accomplished by.providing an upward extending ear 36 on each'free end of frame 31shaped pivoted at the end corresponding to the bottom ofthe Uand havingthe wheels' (sa-id frame 31 being U A30 tions of, the rims of wheels 17and 18, are

The wheels zontal plane and all three of these wheels 17 and18. as clearly shown in Figs. 5 and are normally pressed downward by the15 v6, have their peripheral rims made in secsprings 33. 8o tions, inthe drawing each section is shown A stop 45 is provided for lever 42 topreeS being Seellled 'B0-the hub 0f the Wheel by vent the wheel 19 frombeing, lifted too high e SingleSPOke, and iS PYOVded On'tS 011e when thewheels 12, 13 and 14 are raised by side with a cam track 4 0, which isengaged. the movement of lever 39 as described. by the idler 41 as thewheel is rotated, as While the machine as thus described will 85 seen inFig. 5. The spokes of the wheels 17 perform the operation of pressingthe two A and 18 are made to have a certain amount of abutting edges oftwo pieces of veneer spring and as the wheels are rotated and tightlytogether it will also do the further the cam tracks. 40 successivelyengage the and final work of securing a tape over the idlers 41, theSeCtOIlS 0f lG he lWheel IimS are meeting edges of the two pieces ofveneer 9o SIICCeSSiVely IeSSed and IIIOVed 'COWaId each so as to retainthem in their juxtaposition other, the id ers 41 being stationary andloafter having passed through the -machine. cated on opposite sidesofthe wheels 17 and The tape 46 which may be cloth or paper 1 18. Thepartsare so arranged that the secis preferably wound on a roll 47supported on a reel 16 secured to a standard 48 mount- 95 ed onthebracket 34. The standard 48 also supports the water receptacle 15 whichis rovided with the water carrying rolls 49 and idlers 5() and 51. Thetape 46 passes from the roll 47 over the top roll 49, thence 100 aroundidler 50, thence again over the uppermost roll 49 thence over idler 51thence over the curved protecting shield 52 and finally under wheel 13where it is tightly pressed against the veneer below `the same. 105 Thetape 46 on roll 47 has one side prepared with gum or glue and in passingover roll 49, the Gum or glue is moistened so that the strip whenpressed against the veneer below wheel 13l will tightly adhere to the11o same. To assist in the adhesion and drying of the gum or lue on thetape 46, the wheel 13 is constant y heated by any means as agas burner.53 within the `same. The shield 52 is made of non-heat-conducting 115material so as to rotect the tape 46 from the heat thrown o by the wheel13.

Of' course the ta e 46 is secured centrally over the meeting ine of thetwo pieces -of veneer and laps as much over the one piece 12o of veneeras over the other piece of veneer.

To guide the two pieces of veneer into the machine so that --theirabutting edges will always register centrally under the wheel 13 andthetape 46, a long thin upwardly ex 125 tending blade 54 is secured on thetable 11, having its one end closeto wheel 13 and its other endextending at lright angles to the verticalplane in which the shafts 20and Z9 j lie. The gas for the burner 53 is supplnzd me moved toward eachother while the twol pieces of veneer are tightly clamped between thesewheels 17 and 18 and the wheels 12 and 14, and thus press the edges ofthe l-two pieces ofveneer tightly together. The upper wheels 12 and 14are constructed with sectional rims similar to the wheels 17 Vand 18 andof course the sections which are tightly pressed against the pieces ofveneer when the same is moved by the idlers 41 will move with the piecesof veneer by reason of the frictional contact therewith.

It is understood that the spring in the spokes tends to hold the dierentsections '45 of`the rims of the wheels in their normal position, and assoon as each successive sec. tion passes' the idler 41, so that its camtrack 40 is out of engagement with the idler it is returned to itsnormal position. I`Tlie idlers 41 areplaced in a vertical plane slightlybeyond-.th'e plane in which the point of contact between lwheels 17 and18 and wheels 12 and 14 lies, so that there will be no tendency 4to movethe pieces of veneer apart again 55 when the sections ofthe rims of thewheels are returned to' their normal positions by the spring in thespokes. Obviously the4 particular*construction of the rims of the wheelscouldbemodified without departing from the spirit of the invention.

When the two abutting edges of tw v pieces of veneer are forced togetherthere visa tendency for the edges of the veneer to overlap or buckle andto prevent such action Weprovide the lower pressure wheel 19 beends aregripped between thel upperand` lowerwheels and the vtape 4 6 is ted inungrallylaterally -movable contact members,

der wheel 13... and' then the rotation of.

wheels 17 and 18 on shaft 20 continuato4 feed the pieces of-veneer andthe Vtape along through the machine; as the. successive sections oftherims of wheels 17 and 18 contact with the Aunder side of thepieces ofveneeer they are moved toward ea'ch other -by the action of the idlers41 andtightly press the edges of the two pieceslo veneer Atogether theta'pefl is being p` reSs'ed againSt the'upper surface of the two piecesof veneer. Thusthe-two pieces of veneer leave the machine securely heldtogether by the tape. It will be noted that while passing through themachine, the edges of the pieces of veneer have constantly been in aflat position.

Having thus tullydescribed our invention what we claim as new and desireto secure by Letters Patent of the UnitedStates is:
